<p>7D has better ergonomics, build quality, viewfinder, auto focus system, speed (frames per second), environmental sealing, and lens micro adjust.<br>

T2i is small and light. Has great image quality and video quality.<br>

Overall image quality for stills and video is very close to the same, in fact the T2i seems to have slightly lower noise. But the 7D is a much better built camera and should superior auto focus results in high speed situations. Definitely try them both before you buy.</p>

<p>We'll just have to agree to disagree then. I don't want to offend anyone but for me this is not in question. I also understand and believe that not all pixels are created equal, but the T2i is no slouch, and certainly not far enough behind the 5D Mark II to forget about it's 10 megapixel advantage in focal length limited situations. I've tried to explain it the best way I know how, and for some who have not tried it I understand the need to see it with your own eyes. By all means try it for yourself. Just make sure you are in a focal length limited situation, otherwise none of this applies.</p>

<p>Why is this so hard to understand? It should not even be up for discussion, it is fact that the Rebel T2i will put more pixels on the subject than a 5D Mark II and it will have a ton more detail when you are focal length limited by your lens.<br>

Let's use the example of a wildlife photographer with a 5D Mark II, Rebel T2i, and a 400mm 5.6 Canon L lens. If he shoots the same subject at the same distance using that lens on both cameras, and then crops the 5D Mark II by 1.6 to equal the T2i reach, he will only have 8.2 megapixels left. And yes, you can absolutely see the difference between 8.2 and 18 megapixels of detail. If he wanted to approximately equal the detail of the T2i in the same situation, he would need to use the 600mm F4 L on the 5D mark II.<br>

In this same (focal length limited) situation, the Canon 1.6 crop cameras that only equal the 5D Mark II, are the 20D and 30D. All 3 will put the same number of pixels on the subject using the same lens.</p>
